Help - Swapping of Two Panels triggered by JButtons in two separate Panels

Question

Problem: How to swap two Independent JPanels? Is it really possible?
Some Information:
Scenario 1:
This implementation is easy if both panels was inside a Master Detail Panel (Add the first Panel and hide and remove if the Second Panel is triggered)
//Sample Coding
private JButtonTrigger_actionPerformed(ActionEvent e){
FirstPanel.setVisible(false);
FirstPanel.remove( );
MasterDetailPanel(add.SecondPanel, null);
SecondPanel.setVisible(true);
Note: Assuming that the JButton was placed on Master Detail Panel
Scenario 2:
This is also easy if both are JFrames. In this sample code, This JFrame is calling another JFrame named Main( )
//sample coding
JFrame frame = new Main( );
//Dimension screenSize declaration
//getScreenSize( );
//Getting the height and the width
//Setting the location
frame.setVisible(true);
*** Now this is my problem, Is it really possible swapping two INDEPENDENT JPanels?
Given
1. There are two JPanels, (JPanelFirst, and JPanelSecond)
2. JPanelFirst has JButton named "CallSecond", placed below of it.
3. JPanelSecond has JButton name "CallFirst", placed below of it.
4. "CallSecond" JButton must call JPanelSecond and "CallFirst" JButton must call JPanelFirst when the user presses the button.
5. The principle is swapping.
I have tried to implement this one but the swapping of JPanel does not work properly. I really need your help (sample code or sites recommended) and advice if it is really impossible to implement so that I have an alternative. Thanks for your time reading this.
